Paul McCartney's Heather birthday

(femalefirst.co.uk) - Sir Paul McCartney will spend his 65th birthday with estranged wife Heather Mills.The Beatles' legend has invited Heather to the intimate celebrations at his Peasmarsh estate next Monday (18.06.07). A source told Britain's Sunday Mirror newspaper: "We are talking about a total and very quick transformation from a state of complete vitriol between the two of them to something much more amicable.

"Before she went to America, they wouldn't speak on the phone, now they can have a civil conversation.

"It's as though Paul has chosen saturation point with all the bitterness and Heather - aware of the battering her public image has taken - has decided to genuinely try to bury the hatchet. "Paul has had enough of all the spite. The divorce has effectively been placed on hold."

Heather - who has been embroiled in a bitter divorce battle with Paul since they split in May 2006 - is set to present Paul with a vegan birthday cake at the party. Two weeks ago, Heather, 39, and Paul were seen meeting in a North London restaurant, sparking rumours they had decided to end their feud for the sake of their three-year-old daughter Beatrice.

Relations between them have improved so much friends claim they have been meeting regularly and that Paul even sends Heather "little notes and flowers".

Last week, Paul wowed a select group of fans at a secret London concert.The star, who performed for just 1,000 people, debuted tracks from his eagerly anticipated new album, 'Memory Almost Full' and delighted the crowd with a series of Beatles classics, including 'Hey Jude', 'Get Back' and 'Back In The USSR'.
